I think over a decade all hard drives are perpendicular. I am surprised how they maintain 120 MB/sec if they are SMR but then again perhaps it is expected to have them at that level.
I am planning to use them for WORM scenario but I need them to run 24/7 . They are from COSTCO, there is always the window of 90 days to return them if I have a change of heart or if they fail. I am not sure if Costco will accept them if I have open packages, anyone knows?
@Fritz , did they fail when they were under I/O over 5% average disk time. or simply because their motor is low quality (not sure if there is really different quality motors for hard drives) and die while spinning idle?
